These juicy, slow-smoked chicken thighs feature a bold Cajun blackening seasoning that forms a flavorful dark crust on the tender and crispy bone-in thighs.

Thighs are really in a league of their own when it comes to chicken—moist, succulent meat encased in crisp, golden skin. This slow-smoking method will give you juicy, perfectly cooked chicken thighs every time.
Here, we use the classic, bold-flavored Cajun blackening seasoning, packed with a smoky and spicy taste. This Louisiana favorite gives the thighs an addictive, dark coating that will have you digging back in for more.
What is Blackening Seasoning?
A bold and flavorful spice blend, blackening seasoning is traditionally used to coat chicken and fish. The spices char as the meat cooks, creating a dark crust on the meat’s exterior—hence the name “blackening”. The seasoning hails from Louisiana and finds its roots in Cajun cuisine, using spices and herbs such as paprika, cayenne pepper, and dried oregano.

Why Go Bone-In Thighs Over Boneless
Bone-in chicken thighs are often preferred over boneless, as their higher fat content helps them retain more moisture and flavor during the smoking process. They act as a natural barrier to shield the meat from intense heat and as a conductor that helps cook the chicken more evenly. The marrow from the bone also seeps into the thighs, giving them more flavor.
Skin-on thighs are always my preferred choice as the chicken’s outer coating provides a salty, delicious crunch as you sink your teeth into it, and provides much more flavor than their skinless counterparts.
Even if you do prefer chicken without skin or bone, I strongly recommend that you prepare and cook these with everything still attached, and then remove them after. They will taste far better and retain more moisture during the cook. The bones and the skin act as insulators, allowing the meat to cook gently and evenly, while simultaneously locking in moisture and flavor. You can easily toss the skins after if you so wish.

How to Smoke Chicken Thighs
These thighs are pretty straightforward as far as smoking goes, so set aside an afternoon and make this your next BBQ favorite.
- Remove the chicken thighs from the refrigerator about an hour before cooking to help them cook evenly
- Preheat the smoker to 250°F (120°C). The chicken will cook slowly at this low temperature and remain moist
- Mix the ingredients for the blackening seasoning; this will create a crust on the chicken as it cooks and provide flavor
- Brush the chicken thighs with olive oil and season all over to coat fully
- Place the chicken in the preheated smoker and cook for 1½-2 hours or until the internal temperature reaches 165°F (74°C)
- Remove the cooked thighs from the smoker and rest them for 5 minutes. As the meat cools, it reabsorbs the juices, which keeps it moist
Quick Tips
- Don’t Overcrowd the Smoker: Leave some space between the chicken thighs on the rack to allow for proper air circulation and even smoking
- Dry the Thighs Thoroughly: Before applying any seasoning or olive oil, pat the chicken thighs dry with paper towels to help the skin turn crispy and golden as it smokes
